Many thanks for your guidance.
I decided that it is better to ask the partners to participate in the data collection using a KOBO account so they can have access to the data they submited between the different rounds of data collection.
I do the process of setting up permissions (settings-sharing-who has permission- can ) and the other user can successfully submit forms. here is how the prmission is set
But I have two issues.
In my data table (user name ) shows that my account (owner) has submited all data, although some records was submited by another user that I shared the project with.
the user that I share the project with, cannot see the submited data in her account.
What could be the case?
Thank you so much for all the support.
